Plenty of spacecraft have spheres poking out, lots of hypothetical craft are mostly sphere or just a mostly featureless cylinder or cone. They look ungainly for atmospheric flight but they wouldn't need to be since most of the concepts I can see have a shuttle bay for atmospheric craft. They're too small for interstellar ships though unless you just want to hurl unmanned probes out there. Steel alone can easily get you ships multiple kilometers in diameter and length even if they're spinning fast enough to generate 1g faux gravity.
